All statements other than statements of historical fact contained in this Presentation are forward-looking statements, including statements concerning the Company’s expected capital needs, cash runway and use of proceeds. Forward-looking statements herein generally relate to future events or the future financial or operating performance of SPAC, the Company or the combined company expected to result from the Business Combination (the Combined Company ). For example, projections of future financial performance of the Company or the Combined Company, the Combined Company's business plan, other projections concerning key performance metrics, the proceeds of the Business Combination and the Combined Company's expected cash runway, the potential effects of the Business Combination on SPAC and the Combined Company, the satisfaction of closing conditions to the Business Combination and the timing of completion of the Business Combination, are forward-looking statements.

Such forward-looking statements are based on beliefs and assumptions and on information currently available to management of the Company and are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from those expressed or implied by such forward- looking statements. These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by SPAC, the Company and its management, as the case may be, are inherently uncertain and subject to material change. There can be no assurance that future developments affecting the Company will be those that it has anticipated. New risks and uncertainties may emerge from time to time, and it is not possible to predict all risk and uncertainties.

California Net Energy Metering Regulations Update What is Net Energy Metering? The Push for Reform • Net Energy Metering (“NEM”) is a billing mechanism for California’s investor-owned electric • Some argued that the NEM 2.0 regime was misaligned with California’s grid reliability and utilities whereby customers who install on-site generation such as rooftop solar are eligible to climate change goals receive financial credit on electricity bills for any surplus generation sent to the grid • NEM customers intermittently import and export energy throughout the day without • Utility credits customer for the value of energy 20% exported at prevailing electricity rates consideration for when energy is needed the most • NEM has been active for over 20 years, with modifications from time to time • Output from solar declines in the evening peak hours resulting in ramped up generation from Battery Storage fossil gas plants, increasing greenhouse gas emissions • Opponents argue that NEM 2.0 disproportionately burdened non-solar customers Attach Rate How Net Metering Works • Solar customers viewed as relying on the grid during peak hours while avoiding payment = 200,000 units 1 for the maintenance of infrastructure Solar panels • Higher income customers are more likely to own solar systems generate electricity 3 Excess energy from solar panels sent back to grid In December 2022, the California Public Utilities Commission adopted their latest iteration of the NEM rules, dubbed NEM 3.0, which significantly supports the push for co-located battery 4 storage with residential solar stations. The package includes: Utility credits electricity bill for Switch to Time of Use (“TOU”) billing whereby credits received by homeowner ✓ value of energy sent to grid are the highest during peak hours Homeowners with storage can store energy during off-peak hours, exporting ✓ when TOU pricing is highest Under NEM 3.0, average 2 Additional credits available to customers who install solar plus storage in the residential customers installing ✓ next 5 years Home uses electricity solar paired with battery storage from solar panels and will save at least $136 per month $900M of state funding available in incentives for homeowners who adopt a solar ✓ from the grid during the first year plus storage system, 70% of which is targeted for low-income customers California’s recently adopted NEM 3.0 rules could be a catalyst for the residential storage industry Source: Decision 22-12-056, Decision Revising Net Energy Metering Tariff and Subtariffs, issued 12/19/2022; California Public Utilities Commission Fact Sheet, Modernizing NEM to Meet California’s Reliability and Climate Goals published 11/10/2022.

Risk Factors • Electriq is a relatively new company with a history of losses, and we expect to incur significant expenses for the foreseeable future. We cannot be certain that we will achieve or sustain profitability. • Electriq’s limited operating history and its rapidly evolving industry make it difficult to evaluate Electriq’s business, the risks and challenges it may face and future prospects. • Electriq’s operating and financial results and growth forecast rely in large part upon assumptions and analyses developed by Electriq. If these assumptions or analyses prove to be incorrect, Electriq’s actual operating results may be materially different from Electriq’s forecasted results. • The energy storage industry is highly competitive and rapidly changing. Our business may be adversely affected if we cannot adapt quickly and effectively. • A recession could reduce demand for our products and materially harm our business. • Potential tariffs or a global trade war have increased our costs and could further increase the cost of our products. • Almost all of our revenues in 2020, 2021, and 2022 were derived from 2 customers, and one of our customers accounted for greater than 85% of our revenue in 2022. This customer has notified a supplier of ours that it is exiting the business and thus was ending their customer relationship with us. Accordingly, we do not expect to generate any revenues in 2023 from that customer relationship. • There is no assurance that non-binding letters of intent and memoranda of understanding included in our projections will be converted into binding contracts. Our counterparties may cancel or delay entering into contracts based on the non-binding letters of intent and memoranda of understanding. We expect to derive a large portion of our revenue from installations that are associated with contracts with government entities. Contracts with government entities are subject to a number of challenges and risks. If we are unable to enter into such contracts on a timely basis, our growth, revenue and results of operations may not meet our projections. • We rely on a small number of third party suppliers. This reliance on third parties increases the risk that necessary components of our products may not be delivered according to our schedule and at prices, quality levels and volumes acceptable to us. • We have projected that the majority of our revenue in 2023 will be derived from Sustainable Community Networks. We have not generated any revenue from Sustainable Community Networks in the past. There can be no assurances that we will meet our projects for Sustainable Community Networks in 2023, or that we will be able to generate revenue from Sustainable Community Networks in the future. • We expect to rely on project finance capital to fund installation of our products in the Sustainable Community Networks market, and that funding may be unavailable or expensive. • We expect to have one main source of financing for the Sustainable Communities Networks in 2023. If there is a breach of that financing arrangement, it could have an adverse effect on our liquidity and our revenue and results of operations may not meet our projections. Strictly Confidential / Not for Redistribution 43
Risk Factors (Cont’d) • A significant portion of our purchased components are sourced in a small number of foreign countries, exposing us to additional risks that might not exist if our suppliers were more geographically diversified or were located in the United States. • Increases in costs, disruption of supply or shortage of materials, in particular for inverters and lithium iron phosphate cells, could harm our business. • The ongoing COVID-19 pandemic has impacted and may continue to adversely affect our supply chain, demand for our products and our business. • Our hardware and software integrated energy storage solution may not achieve broad market acceptance, which would prevent us from increasing our revenue and market share. • If demand for energy storage solutions does not grow or grows at a slower rate than we anticipate, including as a result of the ongoing COVID-19 pandemic, our business will suffer. • We depend on a small number of wholesale dealers and installers to assist in selling our products to customers. As our business grows, we will be required to find a significant number of additional dealers and installers. Loss of dealers or installers, the failure of dealers or installers to perform as expected or the inability to find additional dealers and installers could harm our business and impair our ability to meet our projections. • The success of our energy storage system may depend in part upon our ability to continue to work closely with leading solar module manufacturers. • A drop in the retail price of electricity derived from the utility grid or from alternative energy sources may reduce demand for our products and impact our ability to meet our projections for growth, revenue and results of operations. • The reduction, elimination or expiration of government subsidies and economic incentives for on-grid solar electricity applications and/or energy storage systems could reduce demand for solar photovoltaic systems and/or energy storage systems and harm our business. • We may, in the future, experience delays or other complications in the design, manufacture, launch and production ramp of our energy storage products which could harm our business, prospects, reputation, financial condition and operating results. Our planned expansion of our business could also subject us to additional business, financial and competitive risks. • We may experience material disruptions to our operations, including, but not limited to, natural disasters, terrorist attacks or other catastrophic events.
